Hrm, and now I can't get GLUT to build 64-bit again.  For now I'm using 
the prebuilt 32 + 64 package. Both 32-bit and 64-bit python are able to 
run basic glutinit tests.  I haven't done any testing with GLE yet.  If 
people with 64-bit Windows want to test it:

     bzr branch lp:pyopengl
     cd pyopengl
     python setup.py develop
     cd tests
     python test_glutinit.py

should produce a blank black window with a lot of debug blather on the 
console.

HTH,
Mike
